The category of the sociativity in Russian and Serbian languages Категория совместности в русском и сербском языках

Предмет проучавања овог функционално-граматичког, конфронтативно- типолошког дисертационог истраживања из области лингвистичке русистике је дифузна полицентрична структура категорије социјативности у руском и српском језику, коју сачињавају њени морфосинтаксички, синтаксички, лексички, лексичко- граматички и дериватолошки категоријални центри, при чему се пажња усмерава и на сагледавање њихових системских односа, остварених на реченичном нивоу. Уводна запажања посвећена су питањима разграничења и груписања показатеља инваријантне и варијантне социјативности, на којима се заснива и категоријална дефиниција значења друштва, које се у градуелном остварењу инваријантних чинилаца облигаторног статуса темељи на социјативној нејединичности и подударности семантичких функција учесника категоријалне ситуације. У другој глави истраживања спроведена је синтаксичко-семантичка анализа конструкција са социјативним инструменталом у руском и српском језику, у чији састав улазе прави социјативи, најзаступљеније конструкције за исказивање доминантног значења друштва, и псеудосоцијативи...The object of this functional-grammatical confrontative-typological dissertation study in the field of the Russian linguistics is the diffuse polycentric structure of the sociativity category in Russian and Serbian languages which is composed of morphosyntactic, syntactic, lexical, lexical-grammatical and derivative categorical centers with regard to the perception of theirs systematic relations realized on a sentence level. Introductory opservations were dedicated to demarcation and groupings indicators of the invariant and variant sociativity which is the fundament of the categorial definition of the sociativity meaning. In the gradual realization of invariant obligatory factors it is based on the sociative nonsingularity and the accordance of semantic functions of the categorial situation participants. In the second section of this study the syntactic-semantic analysis of constructions with sociative instrumental in Russian and Serbian languages was performed including real sociatives, the most frequent constructions for the sociativity expression, and pseudo-sociatives..

Krvne grupe u alkoholičara

A study was carried out on two population cohorts during two years to differentiate alcoholics from the rest of population in respect of the incidence of blood groups. The subjects - alcoholics and nonalcoholics, were male workers aged 40-60 years who had retired as disabled during the current or previous year. One cohort consisted of two groups of 34 subjects each, alcoholics and controls, in whom the blood groups of the ABO system and Rh blood groups were determined, The other cohort included two groups of 120 subjects each, who had their ABO, Rh, as well as Kell, P, MN, S, C and E blood groups determined. The criteria for entering the group of alcoholics were based on daily intake of alcohol and duration of alcohol abuse. The control group consisted of the workers who drank occasionally minor amounts of alcoholic beverages. Data processing failed to reveal any statistically significant difference in the distribution of blood groups between alcoholics and control subjects.Ovo istraživanje, diferencijacija alkoholičara od ostale populacije s obzirom na zastupljenost krvnih grupa, sprovedeno je u dva dijela s vremenskim razmakom od dvije godine. U oba slučaja ispitivane skupine sačinjavali su alkoholičari i nealkoholičari, muškarci, u dobi od 40 do 60 godina, koji su u tekućoj ili prethodnoj godini stupili u invalidsku mirovinu. U prvom dijelu formirane su dvije skupine od po 34 ispitanika, alkoholičari i poredbena skupina, kojima su određivane krvne grupe ABO sustava i Rh krvne grupe. U drugom dijelu obrađene su dvije skupine od po 120 ispitanika, te su im osim spomenutih krvnih grupa određivane i krvne grupe Kcell, P, MN, S, C i E. Kriteriji za formiranje skupina alkoholičara u oba slučaja bili su dnevna konzumacija alkohola ,i alkoholičarski staž. U poredbene skupine uzeti su samo oni koji su pili povremeno manje količine alkohola i nikad se nisu opijali. Obradom dobivenih podataka nisu nađene statistički značajne razlike u distribuciji krvnih grupa u alkoholičara u odnosu na poredbenu skupinu

Biocompatibility of a new nanomaterial based on calcium silicate implanted in subcutaneous connective tissue of rats

The aim of the study was to investigate rat connective tissue response to a new calcium silicate system 7, 15, 30 and 60 days after implantation. Twenty Wistar albino male rats received two tubes half-filled with a new calcium silicate system (NCSS) or MTA in subcutaneous tissue. The empty half of the tubes served as controls. Five animals were sacrificed after 7, 15, 30 and 60 days and samples of the subcutaneous tissue around implanted material were submitted to histological analysis. The intensity of inflammation was evaluated based on the number of inflammatory cells present. Statistical analysis was performed using one way ANOVA and Holm Sidak's multiple comparison tests. Mild to moderate inflammatory reaction was observed after 7, 15 and 30 days around a NCSS while mild inflammatory reaction was detected after 60 days of implantation. In the MTA group, mild to moderate inflammatory reaction was found after 7 and 15 days while mild inflammatory reaction was present after 30 and 60 days. There was no statistically significant difference in the intensity of inflammatory reactions between the tested materials and control groups in any experimental period (ANOVA p>0.05). Regarding the intensity of inflammatory reactions at different experimental periods, a statistically significant difference was observed between 7 and 30 days, 7 and 60 days and 15 to 60 days for both materials. For the controls, a statistically significant difference was found between 7 and 60 days and 15 and 60 days of the experiment (Holm Sidak < p 0.001). Subcutaneous tissue of rats showed good tolerance to a new calcium silicate system. Inflammatory reaction was similar to that caused by MTA. [Projekat Ministarstva nauke Republike Srbije, br. 172026

Optical conductivity and vibrational spectra of the narrow-gap semiconductor FeGa3_3

Intermetallic narrow-gap semiconductors have been intensively explored due to their large thermoelectric power at low temperatures and a possible role of strong electronic correlations in their unusual thermodynamic and transport properties. Here we study the optical spectra and vibrational properties of $\mathrm{FeGa_3}$ single crystal. The optical conductivity indicates that $\mathrm{FeGa_3}$ has a direct band gap of $\sim 0.7$\,eV, consistent with density functional theory (DFT) calculations. Most importantly, we find a substantial spectral weight also below 0.4~eV, which is the energy of the indirect (charge) gap found in resistivity measurements and ab initio calculations. We find that the spectral weight below the gap decreases with increasing temperature, which indicates that it originates from the impurity states and not from the electronic correlations. Interestingly, we did not find any signatures of the impurity states in vibrational spectra. The infrared and Raman vibrational lines are narrow and weakly temperature dependent. The vibrational frequencies are in excellent agreement with our DFT calculations, implying a modest role of electronic correlations. Narrow M\" ossbauer spectral lines also indicate high crystallinity of the sample

Inflammatory bowel disease and pregnancy

Upalne bolesti crijeva često zahvaćaju žene generativne dobi. Često se postavlja pitanje utjecaja trudnoće na prirodni tijek bolesti, utjecaja same bolesti na tijek i ishod trudnoće te sigurnosti primjene lijekova u trudnoći. Žene s upalnom bolesti crijeva u pravilu mogu očekivati normalan tijek trudnoće te rađanje zdravog novorođenčeta. Aktivnost bolesti prilikom koncepcije najvažniji je čimbenik koji utječe na tijek i ishod trudnoće. Terapija koja se uobičajeno koristi za liječenje upalnih bolesti crijeva sigurna je za primjenu u trudnoći. Na temelju prikaza slučaja bolesnice s prvom manifestacijom ulceroznog kolitisa u trudnoći prikazati ćemo utjecaj bolesti na tijek i ishod trudnoće, utjecaj trudnoće na prirodni tijek bolesti te sigurnost primjene lijekova za liječenje upalnih bolesti crijeva u trudnoći.Inflammatory bowel diseases often affect women during their reproductive age. The questions regarding the effect of pregnancy on the natural course of inflammatory bowel disease, effect of inflammatory bowel disease on the course and outcome of pregnancy and safety of medications used to treat inflammatory bowel disease during pregnancy arise quite often. In general, women with inflammatory bowel disease can expect to have a normal pregnancy with delivery of a healthy newborn. The most important factor influencing the effect of disease on the course of pregnancy is disease activity at conception. Medications routinely used for the treatment of inflammatory bowel diseases can be used safely during pregnancy. Acase of first presentation of ulcerative colitis in pregnancy is presented with review of disease course during pregnancy, influence of disease on pregnancy course and outcome and safety of medications used to treat inflammatory bowel diseases during pregnancy

Tracking variations in daily questionable health behaviors and their psychological roots: a preregistered experience sampling study

People resort to various questionable health practices to preserve or regain health - they intentionally do not adhere to medical recommendations (e.g. self-medicate or modify the prescribed therapies; iNAR), or use traditional/complementary/alternative (TCAM) medicine. As retrospective reports overestimate adherence and suffer from recall and desirability bias, we tracked the variations in daily questionable health behaviors and compared them to their retrospectively reported lifetime use. We also preregistered and explored their relations to a wide set of psychological predictors - distal (personality traits and basic thinking dispositions) and proximal (different unfounded beliefs and biases grouped under the term irrational mindset). A community sample (N = 224) tracked daily engagement in iNAR and TCAM use for 14 days, resulting in 3136 data points. We observed a high rate of questionable health practices over the 14 days; daily engagement rates roughly corresponded to lifetime ones. Both iNAR and TCAM were weakly, but robustly positively related. Independent of the assessment method, an irrational mindset was the most important predictor of TCAM use. For iNAR, however, psychological predictors emerged as relevant only when assessed retrospectively. Our study offers insight into questionable health behaviors from both a within and between-person perspective and highlights the importance of their psychological roots. © 2023, Springer Nature Limited
